It is perfectly OK to set $RecursionLimit to a higher value in some 
portion of the code you write with a Block construct (so it does not 
interfere with the rest of Mathematica and the value is automatically 
reset to its default when the Block construct is exited). For instance,

Block[{$RecursionLimit = 2000},"...your code that need lot of 
recursions..."]
